g. Align a series of images using simple translation (for equatorially mounted
telescopes).
h. Drizzle alignment and resolution enhancement for either equatorial (translation
only) or alt-az (translation + rotation).
i. Colors in Motion (beta): Simultaneous over-sampling alignment and De-Bayer of
one-shot color images to significantly decrease color error and increase
resolution. For one-shot color imagers, this improves resolution and reduces
color error.
j. Adaptive scaling of combined data (stacks) to use full 16-bit range (gives you the
best features of adding and averaging frames).
k. Average a series of images without alignment (e.g., for combining darks, flats,
bias frames, etc.)
l. Tools to set the minimum of an image to zero (useful if a computation has taken it
above 65,535 and you wish to save the image) and to rescale the intensity of an
image (multiply each pixel by a constant).
m. Color balance adjust (offset and scaling) with real-time 3-color histograms for
easy, accurate balancing. Luminance extraction provided as well.
n. De-mosaic a RAW one-shot color image for any of the supported cameras. Both
interactive and batch-mode supported. Pixels become square in the process if
native pixels were not square.
o. 2x2 binning of images: addition, averaging, or adaptive.
p. Blurring of images (3 levels)
q. Crop tool
